Fig. 2E of the application shows the prior art, specifically Google Glass, the disadvantages of which the invention seeks to overcome.
Those having spent too much time on the Internet will recognize Fig. 2E as a line drawing of the infamous Robert Scoble shower image. Scoble posted the image of himself wearing Google Glass while naked in the shower in April 2013. It became to epitomize everything that was wrong with Google Glass, prompting wired.com to write that "guys like this could kill Google Glass before it ever gets off the ground". Whether Scoble killed Google Glass is anyone's guess, but die it did (kind of not, says Google) and Magic Leap is having a laugh at Google's expense here.
